You notice the joiner door takes 12 seconds to fully close. What action do you take?

• A. Replace the door
• B. Oil the hinges
• C. Do nothing
• D. Screw to adjust

Answer: (D)

When a joiner door closes slowly, the most common cause is binding from misaligned hinges or loosened screws. The right fix is to adjust the hinges by tightening and repositioning the screws so the door sits square in the frame and can swing and latch cleanly. Replacing the door isn’t needed unless there’s actual damage to the door or frame. Lubricating the hinges might help a bit, but it doesn’t correct alignment and is only a temporary remedy. Doing nothing leaves the door slow to close and could hinder rapid sealing during an incident. So, adjusting the hinge screws to realign the door is the appropriate action.
